About this site

This site provides direct access to the official data from the Centers for Medicare & Medicaid Services (CMS) that are used on the Medicare.gov Compare Websites and Directories. The goal of the site is to make these CMS data readily available in open, accessible, and machine-readable formats.

In addition to viewing the data in your browser, you can download the data in a variety of formats. You can also access the data through an Application Programming Interface, or API, which lets developers connect other applications to the data in real time using the same data we use to power the Medicare.gov website.

Works of the U.S. Government are in the public domain and permission is not required to reuse them. An attribution to the agency as the source is appreciated. Your materials, however, should not give the false impression of government endorsement of your commercial products or services. See 42 U.S.C. 1320b-10.
